【摘要】：目前有关高水平女子短跨运动项目身体机能评定的方法和标准研究报道少见。本实验根据女子短跨运动项目供能特点,以广东省体训队女子短跨组6名高水平运动员为研究对象,在夏训前、后期对运动员无氧代谢能力进行了两次相同负荷、相同运动方式的磷酸能原商法(AQ)和乳酸能原商法(LQ)测试,同时测定血样中各常规指标:血红蛋白(Hb)、肌酸激酶(CK)、血尿素(BUN)、血液总蛋白(TP)、白蛋白(A)、球蛋白(G)、β2 -微球蛋白(β2 -mg) ,血浆激素指标:血睾酮(T)、皮质醇(Cor)、醛固酮(Ald) ,综合评定运动员的机体代谢能力的改善与否及专项的项目适应性。结果显示:第二次测试的AQ值较第一次提高了12.7% ,LQ值较第一次下降了32.1 % ,表明机体ATP -CP系统能源储备和供能能力增强,到夏训后期,运动员对本专项产生了良好的项目适应性;血液指标的变化显示在短时间极大强度运动后,常规指标变化不明显(P(0.05) ,T、T/Cor值在短时间大强度运动后有下降趋势,Cor、Ald在运动后都有上升,推测血液激素浓度变化与运动强度相关。本实验结果表明AQ和LQ测试是评定高水平女子短跨运动员无氧代谢能力,供能能力强弱的良好方法,通过AQ、LQ值的大小变化可评定运动专项的项目适应性,同时可测定运动前后心率、血压、血乳酸、血液中Hb、CK、TP、T、
[Abstract]:At present, there are few reports on the methods and standards of physical function evaluation in high-level women's short-span sports.According to the characteristics of energy supply in women's short span sports, six high level women short span athletes in Guangdong Sports training team were used as the research objects. Before and after summer training, the anaerobic metabolic ability of the athletes was subjected to the same load twice.Plasma hormone indexes: serum testosterone, cortisol Corn, aldosterone aldosterone (Ald), comprehensive evaluation of athletes' metabolic ability or not and special item adaptability.The results showed that the AQ value of the second test increased by 12.7% and the LQ value decreased by 32.1% compared with the first time, indicating that the energy storage and energy supply capacity of the ATP CP system was enhanced by the end of summer training.The athletes had good adaptability to the event, the change of blood index showed that the change of routine index was not obvious after the short period of maximal intensity exercise, and the value of T / P / Cor decreased after the short period of high intensity exercise, and the value of Corn Ald increased after the exercise.It was speculated that the change of serum hormone concentration was related to exercise intensity.The results show that AQ and LQ test is a good method to evaluate the anaerobic metabolic ability and energy supply ability of high level female short span athletes. The adaptability of sports items can be evaluated by the change of AQO LQ value.At the same time, heart rate, blood pressure, blood lactic acid and HbCK-TPT in blood were measured before and after exercise.
